in humans. Regardless of the mixture of metals, geomelting isolates these heavy metals in a glass matrix and prevents them from entering the environment, eliminating the threat posed to the surroundings. Radioactive Materials Since the advent of nuclear power plants, nuclear pollution (the dispersal of radioactive materials) has become a problem for the environment. The amount of radiation in radioactive materials may not be safe for living organisms, so it is important for all nuclear pollution to be removed. Nuclear waste naturally remains hazardous for hundreds of years, but when processed with geomelting, radioactive materials are immobilized.
